Duck breathing with mouth open like yawning

[Daisy and Daffy]

My duck is opening her mouth wide open like yawning every 30 seconds or so. It looks like this

And she repeats it about 4 or 5 times. It's not hot, and she's not shaking her tail, does anyone know what this is?

 

[Miss Lydia]

Making any noise when she does it?

Making any noise when she does it?

No, she isn’t. No head bobbing or tail shaking while doing it either. She’s eating and drinking fine but still doing it, and my other duck is fine.

Doesn't look like she has anything stuck in her throat. Lets see if we can get others to reply

How old is your duck?

 

[Daisy and Daffy]

1 year 2 months, she’s a white layer

You mentioned she doesn't shake her tail, but what about her head. Does she shake her head at all?

Also if you look in her mouth, does her throat look red or swollen? Comparing it to another duck may help.

 

[Daisy and Daffy]

So no head shaking, and her mouth looks normal as far as I can tell. She doesn’t do it while eating but when she’s lying down, swimming, etc she’ll do it. Not as often now as yesterday

If it's not constant, her throat and airways are cleared no swelling I would lean toward the yawning motion being her adjusting her stomach.

Does she stretch her neck out when she does it? She could have gotten something stuck and dislodged it.
